If you’re trying to clear the cache on Internet Explorer, it’s highly recommended that you do something else first: Download Microsoft Edge. Microsoft no longer supports Explorer (its old browser), so if you’re still using it, you’re more likely to encounter performance issues and security risks that won’t be fixed simply by clearing your cache.
If you love Internet Explorer and want to continue using it, make sure you install a performance optimizer like Avast Cleanup to give it a hand. Avast Cleanup will help you easily keep your browser clean by removing trace files from your browsing history that slow you down. And it will also help you free up space on your device by removing junk files and unused apps.
Here’s how to manually clear the cache on Internet Explorer:
Click the Tools icon (the gear) at the top of the browser window.
Select Safety > Delete browsing history. This will open a pop-up window.

Click the History icon (clock) on the lower left side of the screen, then Clear Browsing Data.

A force refresh is a simple command that allows you to clear the cache on a single web page — so it won’t clear your entire browser cache. It’s a useful way to maintain fast loading times on sites you use regularly while avoiding cache clutter from sites you visit just once. A force refresh is also helpful if you want to maintain private browsing on a public device that you’re using temporarily.
To trigger a force refresh on a web page you’re currently visiting, use the following keyboard browser shortcut that corresponds with your device:
Windows and Linux: ctrl + F5
Mac: Cmd + F5
If your mobile device is running slowly, you may need to do more than clear your browser caches. You may need to clear your app caches to get rid of temporary files, old messages, and images that take up memory.
If you have an iPhone, you don’t normally have to do too much, because iOS automatically clears the cache to some extent. However, if your device is running slowly, you can manually clear your cache on an iPhone. This process is similar to when you want to clear the app cache on an iPad. You can also clear cookies and history on your iPhone.
Android users should clear their app cache every few months to avoid slowdowns and security issues. If you’re not sure how, check out our guide on how to clear the cache on Android, which includes step-by-step instructions.
Every time you visit a website, your browser downloads data like content and images from the website’s server. That takes time. A browser cache works by storing certain data from web pages locally on your device, so you don’t have to download the same data when you revisit a website. This is meant to speed up your browsing experience.
You can think of your browser cache like your pocket, where, when you go out, you keep items that you use a lot, like your wallet, keys, and phone. If you had to run home every time you needed your wallet, your life would be a lot less convenient.
Like your pocket, your cache stores information that you might need again, such as images and text files for sites you frequently visit. Then, when you go back to those websites, that data loads right away, helping you access the site much more quickly.
Cleaning your browser cache can free up space and help your browser load web pages that might be frozen. Cached data can take up a sizable portion of your RAM, causing your browser and other apps to slow down. It may even cause your browser to crash.
Your cache can also get stale with old data, meaning that your browser is full of outdated data, corrupted files, and other digital detritus from sites you won’t visit again. Stale data is not useful and only serves to clutter your RAM.
Here are a few more reasons why you should clear your cache:
Optimize browser speed: Your browser works faster and is less prone to errors when the data in its cache is fresh and relevant.
Improve app performance: Clearing your cache frees up RAM, helping all of your apps perform at their best.
Protect your personal data: Your cache leaves a trail of breadcrumbs and other web tracking data that could reveal your browsing history to advertisers and hackers.
Access updated site information: Old cached forms may contain old site data that’s since been updated. Refreshing those forms will improve site performance, formatting, and speed.
Clearing your browser cache is a simple bit of maintenance you can do to boost your browser’s overall performance. And it helps strengthen your online privacy. Regularly clear the cache on all of your browsers to keep your digital life clean and smooth.

When you clear your cache, you delete temporary files stored on your hard drive that help sites load faster. Clearing your cache may result in some sites loading more slowly, but new sites you visit could load faster if your browser wasn't bogged down with unnecessary cached files.
Clearing your cache will not delete login credentials or custom settings. If you clear both cache and cookies, some settings and recorded login credentials will get erased, so you’ll need to sign into some sites again if you clear your cookies, too.
Yes, you should clear your cache regularly. How often you need to do this depends on how much you use your browser. Clearing your browser cache can improve your browsing experience, boost the page-load time of the websites you visit, and improve your computer's efficiency.
